The site is free to read. What is charged for is a machine reading the same answers through the API or MCP, and what separates the plans is what you may do with an answer — not only how many you take.

What an answer is

Counted in answers; a reply drawing ten moments is one, fifty is five. A reply costs what it draws — the bars around each moment, its returns, where they sit against the usual — so the count follows the k or limit in your own query string, and you can work out what a call costs before you make it.

A call that runs past the allowance or the rate comes back 429 saying which of the two it was and what had been spent, not just that something was too much.

Display and non-display

A person reading a page here is display use, and it is free. A machine reading the same answers is not, and that is what these plans are for. It is the line the exchanges draw and the one the terms follow.

Showing our answers to someone who is not you — which is what an agent does when it answers a question with one — is redistribution, and it is agreed separately. Write to [email protected].

Before you pay

Terms, Refunds and Privacy. A key is free to take and costs nothing until you ask for one that is not: how to get one.
